Everton have joined the battle for Rosenborg midfielder Markus Henriksen.
The Norway international is a target for Celtic, but the Daily Mail says they face competitor from Everton and Benfica.
Henriksen, 19, said: "There has been interest from clubs in me since I was 15 so I am used to it!
"When it feels like the right time for me, I'll leave and it would need to be at a club where I can play first-team football."
